The 10 newly qualified gardaí will assist in providing additional patrols in the Square and Tralee town centre.
Minister Deenihan says while better road networks provide great opportunities for local businesses, they also make it easier for burglars to travel to and from the Kerry area.
New legislation planned by the Minister for Justice, Frances Fitzgerald, will also keep repeat offenders in prison for longer and act as a significant deterrent.
In addition to the new vehicles for 2015, €27.5 million was invested in new Garda vehicles between 2012 and 2014.
The Government is also strengthening An Garda Síochána for the future by reopening the Garda training college in Templemore and recruiting 550 new Gardaí.
The first intake of 100 new recruits entered Templemore in September 2014 and passed out in April of this year.
A further 200 recruits entered in December 2014 and February 2015, with 250 more expected to begin training later this year.
